G. B. Manjunatha et alii, Frattura ed Integrità Strutturale, 46 (2018) 14-24; DOI: 10.3221/IGF-ESIS.46.02 21 value corresponding predicted values for tests under sea water immersion. The difference in error for load carrying capacity is varies from 0.45 to 8.36%. And the fracture toughness varies from 1.46 to 7.49%.

E XPERIMENTAL VALIDATION OF SENB TEST imilarly, Tab. 9 shows the SENB test for load carrying capacity under sea water immersion that difference in error varies from 3.33 to 8.27%. And the fracture toughness varies from 0.6 to 1% is as shown in Tab.10.
